Screen still black | STM32CubeIDE 1.2.0 and TouchGFX 4.13.0

[MMerc.1]

Hi,

I have a problem with STM32CubeIDE 1.2.0 and TouchGFX 4.13.0.

I use the STM32F746G-DISCO board. First, I created a project with TouchGFX to check if the screen works. It works well !

After that, I created a project with CubeIDE. I configured the pinout manually and I was able to display an image on the board via a .h file.

When I add TouchGFX Generator in "Additional Software", it creates the TouchGFX folder. I changed the .touchgfx file but the screen still black when I launch the project on the target.

Could you help me please ?

It is very important.

Same Problem here with an STM32L4R9 Custom Board with GFXMMU enabled.

I can manually fill the Screen with a Color (DMA2D_R2M) and a picture via .h file. But TouchGFX shows nothing. RTOS is freezing and my code is all the Time in LTDC Error Interrupts ( FIFO Underrund and Transfer Error)

Some ideas?
